I know modern technology is the wave of the future, but the importance of being able to talk to a human voice when you have questions is so important. I have written a children’s book that I am publishing on my own and it is my first, so naturally, I have questions. Communicating through email is just not enough. My book is a little different it contains stickers and I know when looking for sticker manufacturers, so many of them when I googled them or spoke to them mentioned the fact that you could actually talk with someone and they knew from global viral feedback how much this meant to the consumer. It would be a plus if you added that to your venue. Thank you, Susan~
